Purpose: This study was conducted to investigate interrater, intrarater reliability and criterion validity of Kinovea Computer Program (KCP) in cervical Active Range of Motion (AROM) measurements compared with the CROM, as a gold standard valid and reliable tool. Subjects: Sixty four healthy participants in one group with mean age was 22.42±0.84 year, mean height was 160.23±6.17 cm, mean weight was 60.77±6.61kg and mean body mass index was 28.60±1.40. Methods: Digital camera, Laptop with installed Kinovea software and markers were used. The cervical AROM of each subject was measured using KCP by three examiners A, B and C three times in the same setting and get the average, to investigate the interrater reliability. The cervical AROM of each subject was measured by the same three examiners using KCP. Each of the three examiners measured cervical AROM three times in separate occasions using KCP to investigate the intrarater reliability. The cervical AROM of each participant was measured by examiner B using the CROM device three times in the same setting and get the average. The gained cervical measurement angles using KCP measured by the examiner with highest ICC were compared with the gained cervical measurement angles measured using the CROM device, to investigate the criterion validity. Results: There is an excellent interrater reliability of KCP for measuring the cervical AROM; cervical flexion, extension, Rt. side bending, Lt. side bending, rotation to the Rt. and rotation to the Lt. Also, there is strong positive pearson{u2019}s correlation between the gained measurements from KCP compared with those gained from the CROM for cervical movements in all directions at P<0.05. Conclusions: KCP is valid and reliable method for measuring the cervical AROM
